Do you brim the tank?

The only two reasons I can think of not to are:

1. Its money sitting in the tank that people may not have (or can make better use of)
2. Its additional weight to push along reducing economy.

These are exactly my two reasons for never putting more than 10/15 quid in.
 
But the tiny savings will be lost in the frequent visits to a service station.

I fill to the brim every time.

True, the extra mpg would potentially be wiped out by the extra mileage to the petrol station. Maybe not if you have to pass it anyway.

Brings up the do you go to the nearest or cheapest petrol station to fill up. May not be cheaper if its further away.

Premium fuels may mean a bit further trip if you want that extra performance boost, or cleaning agents.

Some people are on a tight budget and also some only do relatively few miles so why fill up if you only do 100miles a week or less.

Tight budget? So filling up 4x £15 is easier on the wallet than doing once at £60?

Low miles = fewer visits surely?
 
Depends what mood I'm in, if I can't be bothered to stand there I'll put in £50, otherwise I put a full tank in which is circa £130.

I often use just over a tank in a week in the RR
 
Well lots of drivers spend ages getting the last little bit of fuel into their tanks,I always put the nozzle in all the way and when it clicks that is it,I do that because I can then work out the MPG any other way is less accurate,there is also another good reason not to brim the tank,ok in this country we get two very hot days a year,but in Spain you could lose your fuel,all cars fuel tanks are designed with a air space at the top,by brimming the tank you remove the airspace,if you were to then park on a slope the fuel could weir over down the overflow pipe and then a vacuum occurs which may well empty the tank,in hot weather fuel expands this can also lead to a empty tank,it is rare but I stick to filling to the nozzle clicks.
 
Some may not have the £60 to lay out in one go. And equally may be very bad at budgeting / saving so even if they did get there, they would not save the £15 a week for the next £60 monthly fill up.

Probably not many Mercedes owners in that position, but generally it can certainly be the case.
 
To the top every time. I have to visit the damm things enough as it is. Why suffer more

My understanding of 'brimming' is just that, filling to the first click with the nozzle fully inserted.
 
I'm with zipdip in only filling until the pump shuts off. I'm not bothered about precise brim-to-brim fuel figures, I just want to keep visits to the pumps down but can't be bothered with all that easing the nozzle back to get the last drop in.
 
These days I rarely brim it, I have an 80 litre tank and am retired so do very few miles these days.

I prefer premium fuel so if at say a BP or Shell then I may well fill it as around my area (rural) they are hard to find.

Not a matter of money really.

I believe that's rimming you're referring to.

I don't pull it out till I see the liquid at the top

With respect I don't think you understand a tight budget. I suggest some people, paid weekly, have little left over after paying their other bills, and if they only do 100 miles a week then £15 say will be their fuel budget.
 
I always brim - I need enough to at least get off the forecourt...
 
Always, every time in my own car. I don't understand those who don't, surely people who literally can't afford to fill the tank are massively in the minority?

I don't see as many people obviously being careful about how much they put in as I used to.

However there are fewer filling stations about - a lot fewer. We used to have three within a short distance. They all shut. And along the routes I travel to work there are fewer.

So I think people who used to perhaps budget a given few ££ per week on fuel and fill up every few days as needed have started filling up less frequently and putting in more because they have to travel further out of their way to top up and it's not worth it for small amounts.

I used to feel quite bad not bothering to watch the numbers rack up on the pump - while you would see somebody else watching carefully and assume that for them there was a choice to be made - go a few £ over on the fuel and have less of something else that week.

Mmmm, your definition of rimming is a little different to mine:D
